Compare any two graphics cards:
GeForce 9800 GT 1GB vs GeForce GT 430 1GB
IntroThe GeForce 9800 GT 1GB features clock speeds of 600 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 memory. It features 112 SPUs as well as 56 TAUs and 16 ROPs.
Compare all that to the GeForce GT 430 1GB, which features a core clock speed of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is comprised of 96 SPUs, 16 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce 9800 GT 1GB, in theory, should be a lot faster than the GeForce GT 430 1GB overall. (explain)
Texel RateThe GeForce 9800 GT 1GB should be much (more or less 200%) more effective at texture filtering than the GeForce GT 430 1GB. (explain)
Pixel RateThe GeForce 9800 GT 1GB will be quite a bit (more or less 243%) faster with regards to anti-aliasing than the GeForce GT 430 1GB, and will be capable of handling higher screen resolutions better. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.
Price ComparisonPlease note that the price comparisons are based on search keywords, and might not be the exact same card listed on this page. We have no control over the accuracy of their search results.
Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
